What to do in case of a jellyfish graze?
First of all, we must avoid scratching ourselves, as we can activate some of the jellyfish's toxic cells that still remain inert on our skin. The above also applies to the use of towels, sand or fresh water.
Next, it will be necessary to rinse the affected area with plenty of sea water, and although some popular remedies recommend urine, the safest is vinegar. Being a weak acid, vinegar prevents the nematocysts from "exploding" on the skin causing more pain. In addition to the above, we can apply cold compresses for fifteen minutes to relieve the symptoms of the poison, and it is recommended (in case of intense pain), the supplementation of antihistamines such as diphenhydramine.
The use of corticosteroid ointments or sunscreen can also help reduce inflammation, as can a homemade mixture of baking soda and water. Usually, the wound caused can last between 24 and 48 hours.
In the case of children, we must prevent them from coming into contact with jellyfish, even when they are inert on the shore (even dead, their poison can remain active for hours). If the little one suffers an accident, remove it immediately from the water and try to remove the remains of tentacles (never directly with your hands).
For some symptoms such as severe pain, shortness of breath, or swollen lips, seek medical attention quickly.
